Examples of HSM Model in a sentence
However, this temperature of 600°F is bounded by the blocked vent accident condition of the 24PTH-S-LC DSC in HSM Model 102, which was analyzed based on a shell temperature of 613°F that produced a peak cladding temperature of 821°F which was significantly below the accident temperature limit of 1058°F and consistent with the guidance of ISG 11, Rev 3.
For example, Section D.9.1 of the WCS SAR references Section 7.3.2.1 of the NUHOMS FSAR for information on the 61BTH Type 1 canister and the HSM Model 102 storage module.
The NUHOMS®-32PT DSC is to be utilized in the Standardized NUHOMS® System, consisting of the OS197 or OS197H TC, and the NUHOMS Horizontal Storage Module (HSM), Model 80 or 102.
Specifically, the NUHOMS® MP187 Storage System will use the HSM (Model 80) overpack to house one of three types of approved spent fuel canisters, the FO-DSC, FC-DCS or FF-DSC.
The expressions in parenthesis (e.g. HSM-H(HD), HSM Model 80 (PWR), etc.) are provided for the purpose of this report and associated Microsoft Access database and are not part of the official storage module designations.
Thus, the dose rates for the 24PTH-S-LC in the HSM Model 102 bound the dose rates for the 24PTH-S-LC in the HSM-H.
Notwithstanding the limits established in 5.4.1, the dose rate limits listed below for the Standardized HSM and HSM-H shall be met when a specific DSC model loaded with fuel is stored within a module: Dose Rate Limits for the Standardized HSM and HSM-H DSC Model HSM Model* Applicable only to 24PTH-S-LC.
To implement this change, the applicant proposed to change UFSAR sections 4.2, Storage Structures; 4.10, References; P.4.4.8, Evaluation of HSM-H Performance; chapters R.3, Evaluation of HSM Model 152 Concrete Components with Temperature exceeding Code Limits; R.4, Evaluation of HSM Model 152 Concrete Temperatures; V.3, Evaluation of HSM Model 202 Concrete Components with Temperature exceeding Code Limits; and V.4, table V.4-2 Notes in support of this additional scope item.
The shielding analyses for the 24PTH-S-LC used the HSM Model 102, a standardized HSM, because it has less shielding than the HSM-H.
The staff used simple calculations to estimate the dose rate impacts due to shielding differences between the HSM Model 102 and the HSM-H.
